Two Trees Sapphire Pro Carriage Support + BLTouch (3DTouch - AliExpress) update4: new interface! really cool! https://github.com/vyacheslav-shubin/mks-robin-nano35-binary update3!!! upload My modified MKS firmware for mks robin nano (fork mks v2.0.2): https://github.com/ochkariky/MKS-Robin-Nano-Firmware_compile (add More menu, M48, add UBL support in autolevel menu, increase length name in Print menu.) Resolves the issue of a wobbly head and vibrations along the Y axis and BLTouch mounting. Need to drill and tap just like Jaaanik. Turned out to be very simple! and necessary, because the head on the bracket is swinging up and down along Y as I don't know what! Mounting: 2x M3 6-8mm long 2x M3 19-20mm long. STRICTLY! or else it will hit the bolt of the radiator fan. 2x M3 nuts and 2x M3 screws from the 3DTouch set Original holder by Jaaanik did not please me. In it, the lower attachment points were too far apart (34mm) and the thread was cut too close to the corners and bends. I reduced the distance between the lower holes to 32mm. As a result, the left long screw (20mm) can slightly touch the edge of the bolt that holds the radiator fan. I added shims under the screws - in this case, it does not hit the bolt. Two models for 32mm like mine and for 33mm if you think it's better (there should be no problem). For Chinese 3DTOUCH, a Z probe offset of -1.58 to -2mm was obtained. In the retracted state, the nozzle is already up. update: last file robin_nano_cfg.txt updated update2: Initial code in Cura with nozzle clearance (a bit excessive): G28 ;Home G0 Z5 F3000;++ up 5mm for move G29 P0; UBL reset G29 P1; UBL autolevel G29 P3; UBL interpol G29 A; UBL autolevel Activate M420 S1; autolevel ON G0 Z5 F3000; Up, if g29 -not use! after g29 nozzle be alredy up G0 Y0 X0; ++ G1 Z30.0 F6000 ;Move the platform up15mm G92 E0 G1 F200 E15; extrude 15mm, must remove?

How to make the mesh extrapolate normally on the edges - I have no idea. After shifting the Z endstop, the error in this area changed its sign. At least it doesn't scratch). Update: MKS firmware 2.0.2 released: 1. they say they fixed AUTO_BED_LEVELING_BILINEAR leveling, SafeHome, babystep. They released the sources!!! I'll try auto-level 3. Maybe it will work update2 AUTO_BED_LEVELING_BILINEAR worked, but unpredictably. Again scratched the table. Returned to UBL.
